VAPOR-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 606,721, dated July 5, 1898. Application filed January 13, 1898. Serial No, 666,502. (N model.)

To all whom it may concern.-

Be it known that I, GUsTAF JOHNSON, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare that the following is a full, clear, and exact-description thereof.

My invention has for its object to'obtain 1o the best possible results in the matter of converting hydrocarbon liquid, such 'as petroleum, into fuel-vapor under the influence of heat; and it consistsin certain peculiarities of construction and combinations of parts constituting a simple, economical, and effective vapor generating burner, hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

2o Figure 1 of the drawings represents an elevation of my improved burner,- partly in section, as indicated by line l l in the fourth iigure; Fig. 2, a plan view of the burnerg'Fig. 3, a horizontal section of said burner, indicated I by line 3 3 in the fourth figure; and Fig.' 4t,

another elevation of said burner, partly in section, as indicated by line 4 4 in the first figure.

Referring by letter to the drawings, the head l 3o A of the burner is a preferably dished disk having an annular chamber b therein adjacent to its rim, and cross-channels c d, these channels being open to eachother and said chamber. Depending from the disk at quar- 3 5 ter-circle intervals ofthe same are hollow lugs e f, that communicate with the chamber b,

and these lugs register with the termini of the aforesaid cross-channels.

In duid-tight connection with the disk-lugs 4o are the upper ends of pipes B B C, the iirst two of these pipes being curved branches' of a coupling D, that is provided with a dripcup flange E and has screw-thread connection with a supply-pipe F for liquid hydrocarbon. The other pipe C of the series is U-shaped and has its bend centrally provided with an upwardly-extending jet-nozzle g, this bend being above the coupling D above specified.

In practice the burner is first heated by a readily-combustibleliquid, such as alcohol, 5o

Yignited in the drip-cup iiange, and thus the conversion of the liquid hydrocarbon circulated in said burner is begun. The hydrocarbon liquid is fed to the vaporizing-chamber b of the burner through the pipes B R, and the resultant inflammable vapor finds its way to the outlet-nozzle g of pipe C, this vapor being ignited to serve as fuel.

It has been found in practice that the iiame from the jet-nozzle will extend for some dis- 6o tance above the same, and the dimensions of the disk or burner-head A are such that said flame is diffused so as to burn in a circle, and thus give the best results.

The burner is kept hot by its own flame, the latter continuing as long` as there is supply of liquid hydrocarbon to said burner, and owing to the circulation of this liquid in contact with a very considerable area of heatingsurface it is rapidly converted into free-burn- 7o k ing vapor unmixed with air until it escapes through the jet-nozzle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A vapor-b urner consisting of a disk having an annular chamber therein adjacent to its rim, as well as cross-channels that are open to each other and said chamber, hollow lugs depending from the disk at quarter-circle in- 8o tervals of the same in register with terminals of the cross-channels, a supply-pipe coupling havinghollow branches whose ends are joined to one pair of disk-lugs, a U-pipe joined to the other pair of disk-lugs, and a jet-nozzle extending upward from the bend of the latter pipe, said bend being above the supply-pipe coupling.

2. A vapor-burner consisting of a disk having an annular chamber therein adjacent to 9o its rim, as Well as cross-channels that are open to each other and said chamber, hollow lugs depending from the disk at quarter-circle intervals of the same in register with terminals of the cross-channels, a supply-pipe coupling provided with a drip-cup flange and having the county of Milwaukee and State of Viseonsin, in the presence of two witnesses.

hollow branches joined to apair of disk-lugs, a U-pipe having` its ends joined to the other pair of disk-lugs, and a jet-nozzle extending upward from the bend of the latter pipe, said l 5 bend being above the supply-pipe coupling. In testimony that I claim the foregoing I have hereunto set m y hand, at Milwaukee, in
